Remote Migratory Reductive Arylation of Unactivated Alkenes Enabled by Electrochemical Nickel Catalysis

Transition metal‐catalyzed cross‐coupling reaction between organometallic reagents and electrophiles is a potent method for constructing C(sp2)‐C(sp3) bonds. Given the characters of organometallic reagents, cross‐reductive coupling is emerging as an alternative strategy. The resurgence of electrochemistry offers an ideal method for electrochemical reductive of cross‐coupling electrophiles. Inspired by the mechanism of electrochemical metal hydride, our study proposed that Ni‐H electrochemically catalyze the hydroarylation coupling of unactivated alkenes with aryl halides. 1,1‐Diarylalkanes can be produced effectively. This method have advantages including mild conditions, excellent regioselectivity, and satisfactory yields.
